From: Sprinklerforum <[email protected]> On Behalf Of Travis Mack, SET, CFPS, CWBSP, RME-G Sent: Wednesday, May 22, 2019 9:05 AM To: [email protected] Subject: ESFR and Obstructions - Sizing Can some one help me locate the section in NFPA 13 (2016 preferred) that indicates when you have obstructions below the ESFR sprinklers, you supply the sprinkler below the obstruction with pipe size the same as the branch line and you don't include the additional sprinklers in the calculations? The old method was to calc two additional sprinklers below the obstruction. But I believe it has been replaced with the criteria I mentioned.
